  It's only used opportunistically, though (which is still much better than plaintext).

    > Implying that opportunistic encryption is much better than plaintext Unless you have an active attacker, in which case they are equivalent.

      So, overall, much better :P

      No security measure will 100% prevent attacks; any security measure is about increasing the cost to attackers. Forcing attackers to be active is a good thing on this measure (though of course if you can use a technique that is also effective against active attackers this is better still).

  I said officially announced. Do you have a link from Whatsapp saying that?
